You mean these fellas?

Yeah, it has a pair of low profile slots -- one PCI-X, one PCI. And the built-in Sound Blaster® Live! 24-bit doesn't have a game port, nor, according to this page does it have any kind of dongle/breakout for adding one.

My google-fu is weak this morning. I can't find any low-profile PCI joystick cards, which is basically what you want, I think. USB might be the way forward.
